quotes from Hintikka
"For Hintikka, it is a theorem:
> If S knows that p, S knows that he knows that p.
and asks:
>Where does this get us though?
To symbolism.
Hintikka's theorem, controversial as it may look, is easy enough to
symbolise:
K(A, p) --> K(A, K(A, p))
With 'ignorance' it's a trick
The existence of a correlate to Hintikka's theorem in epistemic logic may
have a reverse in Agnotologics. Or not.
~K(A,p) --> ~K(A, ~K(A,p)).
Cfr. Geary, "I ignore what I'm ignorant of".
